Abstract: An improved understanding of river ice processes in cold regions is crucial due to the impact of ice jams on water levels. Increasing water levels may lead to flooding and cause many problems for communities living near rivers. Monitoring ice processes, including surveying the top-of-ice profile of an ice jam, can be a very time-consuming task and may expose researchers to various hazards. To overcome these challenges, aerial data collection using Unpiloted Aerial Vehicles (UAVs) is a well-known alternative method. In previous studies, top-of-ice profiles have been obtained using discrete data collected by Real-Time Kinematic (RTK) Global Navigation Satellite System (GNSS) survey equipment however, this research fills in the gaps of having a continuous profile for top-of-ice elevation by utilizing LiDAR technology combined with UAV on the Dauphin River in Manitoba, Canada. An 8 km top-of-ice profile was obtained for the Dauphin River and validated with a set of data collected by RTK-GNSS equipment.
